[Overclock the Antminer S1 to 200GH/s] The EASY way! - updated to 393.75MHz ASIC

[broken_pixel]

Hey palawan, can you post the commands for the default frequency of 350MHz and for 375MHz? Much appreciated the heat is building up outside in East Texass as I vent the ass end by a window.  

Sadly, I know what you mean      The codes depend if you used my scripts.  Are you on 400MHz or 393.75MHz?

I am was using the 400MHz script but went to the 393.75MHz, both S1s are avg. over 200GH/s each. I need to get one of my S1s back to the default frequency so I can send Bitmain a screenshot, they want to see the perf. on the one with the cracked heat sink and I don't want to send a screenshot with it overclocked.  

The S1 with the cracked heatsink performs the best and has a super low error rate even at 400MHz, the only issue I see are the temps vary 2 C between the blades as my other S1 vary only 1 C. Not a big deal but I am trying to get Bitmain to compensate me for sending me a unit that should not of passed the QC.

Thanks for the reply.

Thanks for the post. Really helpful and probably will take advantage of this.

Ok, sounds good.  There is always a discrepancy of temp between the 2 blades for me (for both of my S1's).

If you're on the 393MHz, below is the command to switch to default (350MHz):

Code:

clear
cd /etc/config
mv asic-freq asic-freq.393MHz
mv asic-freq.350MHz asic-freq
read -rsp $'Press enter to continue (Antminer will reboot)... ASICs speed set to 350MHz \n'
reboot

In order to go to 375MHz from 350MHz above, the commands are below to copy and paste:

Code:

clear
cd /etc/config
mv asic-freq asic-freq.350MHz
mv asic-freq.375MHz asic-freq
read -rsp $'Press enter to continue (Antminer will reboot)... ASICs speed set to 375MHz \n'
reboot

As you can see, the scripts depend on the current active speed because the files will get jumbled up if you don't keep track.  Good luck

You're welcome.  Hope it works for you and let me know if you have any questions.

Updated to 393.75MHz as this produces 200GH/s with a much lower HW errors (I'm getting less than 1%)

Here's an easy way to oc the Antminer S1.  Disclaimers: I'm not responsible for any damages that may result from following these instructions.  This will void the Antminer S1 3-month warranty.  

If you want to see a youtube video on how it works; here it is:  How to Overclock the Antminer S1 bitcoin miner [the EASY way]

• 1.  ssh to your Antminer  (i.e. ssh root@192.168.1.111)
• 2.  copy and paste everything inside the code box

Code:

clear
cd /etc/config
mv asic-freq asic-freq.before-393MHz
wget -O asic-freq http://dl.dropboxusercontent.com/s/bwbk1wdy0yx1l46/asic-freq.393.75MHz
chmod 664 asic-freq*
read -rsp $'Press enter to continue (Antminer will reboot)... ASICs speed set to 393MHz \n'
reboot

If you must have the 400MHz speed; replace with the code below:

Code:

clear
cd /etc/config
mv asic-freq asic-freq.BitmaintechFactoryVersion
wget -O asic-freq http://dl.dropboxusercontent.com/s/u8thhaxuksnhlw0/asic-freq.400MHz
wget -O asic-freq.375MHz http://dl.dropboxusercontent.com/s/9yuq14py6sou2w3/asic-freq.375MHz
wget -O asic-freq.350MHz http://dl.dropboxusercontent.com/s/o8590pne9clm348/asic-freq.350MHz
chmod 664 asic-freq
chmod 664 asic-freq.3*
ls -la asic-freq*
read -rsp $'Press enter to continue (Antminer will reboot)... ASICs speed set to 400MHz \n'
reboot

Let me know if you have any questions or wish to switch between ASIC speeds (i.e. 180GH/s is 350MHz, ~190GH/s is 375MHz).

so easy! thanks mate!

Hey, not sure if it is just not posted or if I am not seeing it right now but is there code posted for changing from 393 to 387? And 375 to 387?
Thanks!

Oh and if you happen to have the DC codes, I could use those as well in the near future as I am near maxed on my power grid, heh

[NorTiaN]

Hey Palawan, could we have this for the S2?

[arruah]

Thank you. I have to overclock.

[palawan]

Thank you. I have to overclock.

You're welcome.

[palawan]

Hey Palawan, could we have this for the S2?

Sorry but I don't have an S2.  From what I've read on the S2 thread, the mods on the "files" of the S2 SD boot flash are not permanent and have to be re-applied each time the S2 is rebooted.

I can modify an asic-freq with the values of 387 but I cannot guarantee it as I've never run it myself.  Can you provide the values here?

DC codes?  I think there's a thread on pencil mods but I'm not experienced or knowledgeable on it.  Sorry...

Yeah I am looking for the 387 like..

So nobody could figure the freq for 380 or 385? At 393 I get 3% HW error and at 375 I get .08 so I want to try something inbetween. I know in the larger picture it doesn't matter but I am anal about this stuff.

Try this:

Code:

        #option 'freq_value'    '5e85'  #387.5M
        #option 'chip_freq'     '387.5'
        #option 'timeout'       '37'

But I know very little of compiling code etc.

I thought i read in this thread about you having under-clock settings? I am aware of the pencil mod but wanted to try under-clocking the freq first.

Thanks!

I'm not really compiling...  I'm just making the changes to the /etc/asic-freq    I'd love to learn how to code, but it's taking some time as I'm busy at my day job.

If you want to go to 387 MHz, copy and paste the lines below after you've ssh'ed to your S1 as root:

Code:

clear
cd /etc/config
mv asic-freq asic-freq.before-387MHz
wget -O asic-freq http://dl.dropboxusercontent.com/s/c81kk96lu3bvmy6/asic-freq.387MHz
chmod 664 asic-freq*
read -rsp $'Press enter to continue (Antminer will reboot)... ASICs speed set to 387MHz \n'
reboot

Only one frequency can be active at a time.  This 387MHz is for overclocking...

Thank you! Currently I have all my S1 overclocked but I have a couple that are not very fond of the 393 or 400 freq's and figured the 387 would be my next best choice over 375 (or the factory 350). Lemme know if you ever need anything 3D printed and I will hook you up!  
 Thanks again mate!

So, to change the overclock code for another FREQ I would just change the FREQ within the above posted code? Say if I wanted to go to 387.5...



Thanks again mate!

Oh, sorry about that!  I didn't put the extra .5 in the filename, but this is the frequency you supplied.  DO NOT use the code that you posted as it will mess up your S1.  My dropbox does not have that file you posted in your code.  You're welcome mate!

Here; use the code below with the display of the asic-freq file:

Code:

clear
cd /etc/config
mv asic-freq asic-freq.before-387MHz
wget -O asic-freq http://dl.dropboxusercontent.com/s/c81kk96lu3bvmy6/asic-freq.387MHz
chmod 664 asic-freq*

Hello all

   I was planning on overclocking my S1's this weekend using this method for cooling   https://www.youtube.com/watch?v=VOyrCut0y30

   I bought one S1 off of ebay a while ago it seems to run hotter than the other two I had from china   it runs fan 3180  temps 54,53

the other two run fan 2400 temps 47,47 why is that one running hotter it is not overclocked just wondering should I overclock that one I thought I would start with the new ones first.

What is limit on temp or a safe temp

Many thanks
Steve
